Description

Silane, Chloro(4-Ethenylphenyl)Dimethyl- is a specialized organosilicon compound featuring a reactive chlorosilane group and a polymerizable vinylphenyl moiety. This dual functionality makes it a valuable silane coupling agent and monomer for creating hybrid organic-inorganic materials. It is primarily used by R&D and production teams in the advanced materials, electronics, and specialty polymer sectors to enhance adhesion, modify surface properties, and synthesize novel silane-functionalized polymers and resins.

Application

• Silane Coupling Agent: Used to promote adhesion between organic polymers (e.g., epoxies, polyimides) and inorganic surfaces like glass, metals, or minerals in composite materials and coatings.
• Surface Modification: Functionalizes silica, glass fibers, and other fillers to improve dispersion and compatibility within polymer matrices.
• Polymer Synthesis: Serves as a reactive monomer or cross-linking agent in the synthesis of specialty silicones, silsesquioxanes, and other hybrid polymers.
• Electronics & Semiconductor: Employed in the formulation of dielectric materials, encapsulants, and photoresists where specific surface energy and adhesion properties are critical.
• Adhesive & Sealant Formulation: Enhances the bonding strength and environmental resistance of high-performance adhesives and sealants.
• Research & Development: A key intermediate for developing novel materials in academic and industrial research labs focused on nanotechnology and advanced coatings.
